Mosquito fogger is a device that is used to repel or terminate insects, mostly mosquitoes from backyards, gardens, patios and other areas. After you have discovered areas around your house where mosquitoes are living, next thing to do is to choose the most effective time for fogging. There are few important things to note about when it’s best to fog and when you should avoid fogging for safety or efficiency reasons.

When is the best time to fog?

The best time to fog is when the activity of mosquitoes is the highest. Most mosquitoes are active in evenings and only a few species are active during the day. In general, mosquitoes don’t prefer sunlight and are looking for shady areas to hide during the day. The best time for fogging is in early mornings and evenings around dusk. Mostly fogging is done during evenings because of following reasons:

  • In the evening hours and around dusk the day temperature has lowered and most of the time the temperature closer to the ground is going to be higher than that in the air. This allows the fog from an insect fogger to settle on the ground easier and therefore the fog is going to stay in the area for longer time.
  • At this time wind is usually died down, which is very important for a successful fogging session.
  • Most good insects like butterflies and bees are active during the daytime and their activity has ended before the late evening hours and dusk. So fogging at this time won’t harm these good species as much, which is great since most insecticides will not only kill mosquitoes but other small bugs and insects that may do good for your garden and biosphere around the fogging area.

It is also important to fog in low wind or ideally in windless conditions. Low wind conditions are vital for a successful fogging season, because particles of the fog made by an thermal or cold fogger are very small and can be easily moved by a tiny wind gust. Low wind or windless conditions will allow the fog to stay on the area fogged for a longer period of time, which results in more terminated mosquitoes and will also repeal the mosquitoes from that area for longer time. For example, if you fog a bush in higher wind conditions, the fog will immediately get blown away from the bush and low number of particles will settle in that area. This is why fogging in low wind or windless conditions is so vital for great success in terminating majority of mosquitoes in the area.

When fogging should be avoided?

There also are times when you absolutely shouldn’t use a fogger. As mentioned above, it is not advisable to fog in high wind conditions and it is forbidden to fog in a very gusty wind, because of following reasons:

  1. Fogging in a gusty wind makes the fogging process ineffective. Insecticide particles cannot reach the fogging area, because wind blows them away immediately after they have been sprayed out of the nozzle of a fogger. By fogging in high wind conditions you will more likely waste large amount of insecticide rather than making a visible impact on the mosquito population in the area you’re fogging.
  2. High wind gusts can make fogging uncontrollable and the fog can be blown to areas you’re not willing to fog. This may be harmful not only for plants and good insects but also for children, pets and even yourself. This is why FOGGING IN HIGH WIND SHOULD BE AVOIDED AND CAN EVEN BE DANGEROUS FOR THE ENVIRONENT.

If you are fogging in low wind conditions remember to protect your skin from the fog getting on it, because most insecticides contain chemicals which can be bad for your skin. Also fog in direction of the wind and do not stand in crosswind or else all the fog will get blown back to you. And it is also not advisable to use a fogger in very high temperatures.
